Thisv invention relates to improvements in iveatherstrips, and more especially to weather strips adapted to be used in connection with Vswinging closures such as easement Windows,

doors, and the like. An object oli the invention is to provide in lproved Weatherstrip adapted to torni a novel and simple weatherproof joint between a closure and theassociated easement there- 'or When the closure is snfung to closing position. y

A further objectoil the invention is the provision of a. Weat ierstripoil the character described, especially adapted for use upon the lower rail or sill oi a Casement to establish a tight seal between it and the bottom ofthe associated closure.` Y j A further objectgis the provision oi a Weat-herstripr of the character described, which' is ot exceedingly simple construction, .which -iscapable of being very easily and economically manufactured, which can be very easily and quickly installed, and which is capable of eliiciently performing thej'servioes required of it.- lVithfthe Jforegoing and other objects lin View yWhich Willbe inade manifest in the ollowing detailed description and speciiieally pointed out in the appended claims, reference y'is had to the accom aan fine drawings for an ill 1straive embodiment ot the invention, wherein Figure'l is a perspectiveyieiv' ot a case? Y nientivith a easement window inno and showing one oi "the Weathersti ed .then ips oil the present invention mounted upon the to establish a weather-proof joint between the silland tlicivindoiv.'

I Fig.v Zvis u, fragmentary, transverse, sefctional View talenupon tlierline 2 2 oit i? Fig. 3 is al View similar to VFigzQ, shou ing the Window moved ironi'closed position.

` Fig. e is an enlarged View similar to Fig. 2. Fig. 5 is a'perspective view of a portion oi -tlie weatherst-rip.

Y Fig. 6 is a diagrammatic View of the weatherstrip showing in dotted lines the posii tion assumed thereby Vwhen, in released position. Y Y Y Y Y in termsgeit'broad'inclusion, the weather- YVstrip of the present-'invention comprises a Vstrip ot suitable resilient material secured to the cosenient'oi e. hinged closure With va portion of th'fivtrip deiiected from the secured partito' resi iently engage the inside corner 13 extending longitudinally of of the Window. A flange is provided upon the other side of the strip to. engage the outer tace ot the Window, and a plurality ot Weepholes are provided adjacent the base ol' the iiango to permit the escape ot any water which may becoine entrapped therebehind.

In greater detail, the preferred cnibodiment oi' the Weatherstrip or' the present invention is shown positioned upon the lower rail or sill 6 of the easement if within Which easement Window 8 is hung by hinges 9. rEhe Weatherstrip which is indicated in its entirety by the numeral il, is preferably formed of an elongated strip ot resilient, noncorrosive metal such as brass or bronze. lt is bent throughout its length in a tight, reverse bend 12 to provide a double upright flange u the' Weatherstrip il.' @ne ot' theY sides 11i of the iiange 13 extends laterally trein the bottoni oi the flange to provide atastenine edge 1G, the angle between the fastening edge G and the upright Hnge being )reiten ly less than 900 so that "when the'iweatherst L is positioned upon the conventional slopin sill l?, +1e

iienge 13A-vill rextend substantially vertically.

iva 'ds to Apresent "on inclined suriiziee 25) L inst Wh .A corner Si. of the' vwindow 8 may ipinge the Window 8 is being l, to spring theV inclined portion 2e fards troi'n, its releasing position, u is indicated in dotted lines in Fig. 6, nd perniit the Win-dow to pass to tullyelosed osition. lt is to be understood that the l riliency ot the material oiu which es ie weatherstrip is composed, is Veuch that ivlieii the Window 8 is in fully closed position, the inclined. portion 2lik Will ress tightly against the inner lower corner 27 of the Window, to establish a4 tight seal between the -window` ano the sill 17, as slioivn in full lines in 6. j i Y i The proportionate size and arrangement'ot the parts is'such that the outerface of the window strikes the flange 13 just after the inner lower corner 27 has passed the cnrlededge 28 as the window is closing. Thus a double seal is provided against the passage of water or wind between the sill 17 and the window 8.

A plurality of weep-holes 33 are provided adjacent the base of the flange 13 to peimit the escape of any water which might leal; into the space 34 between the bottom of the window 8 and the weatherstrip 11. The upward inclination of the body portion 22 from the flange 31' will preclude the possibility of the leakage of such water to the inside of the easement 7 either by gravity or by capillary attraction. Thusfit may be seen that l have provided an improved type of weatherstrip which is especially adapted to provide a weather tight seal between the bottom of a easement window and the sill; The weath- Verst-rip is of such width that it extends clear j ing the outer face and the angularly inclined body portion engaging the lower inner cor ner. It may be readily appreciated that a weatherstrip of such characteristics is not only capable of efficiently sealing the space between the window and the sill, but is also capable of being very inexpensively manufactured and very easily installed.

The weatherstrip is preferably formed of relatively thin material, suoli as 32-gauge spring metal. When constructed ofv such thin material, it is unnecessary to provide the r w-eatherstripwith holes for the reception of the fastening means 21, as the fastening means may be driven right through the inaterial.

lt is also unnecessary to bend the body portion 22 to provide the inclined portion 24. Instead, the weatherstrip may be secured to the sill 17 while flat, and then a blunt instrument run across the body portion 22, using the fastening edge 16 as a straightedge. By pressing the blunt instrument down hard upon the body portion, the latter may be yscored and bent upwards to provide the inclined portion 24.

Various changes inthe details of construction may berinade without departing from the s-pirit and scopeof the invention as defined by the appended claims.
